I think there were other unpublished stories that Christopher Tolkien found, some of which he filled in himself. I guess you can't expect unfinished rough drafts to be very good, to be fair, Tolkien sr. would probably be horrified to know that people can read them today. They are more for a historical curiosity, I think.

I just think 'spin offs' isn't really the way to classify something like The History of Middle Earth and the other, largely academic works, that Christopher Tolkien has put out. A great deal of that is just annotated notes and much of it predates LOTR.

It's not like he's Frank Herbert's kid, spitting out crappy sequels of his own invention.
